METAL SHEET-PILING.

To all whom it may concern.

Be it known that we, CLOUD O. CONKLING and CHARLES S. BOARDMAN, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Metal Sheet-Piling, of which the following is a specification.

Our invention relates to an integral, interlocking junction member, for use in walls of metal sheet piling either for reinforcing a single wall or as a union for connecting intersecting walls.

Our peculiar, interlocking member is rolled complete in one piece from the steel bloom, and, as a characteristic feature, is provided on the opposite sides of the web and intermediate of the edges, with interlocking elements, adapted to engage with corresponding elements on the edges of the simple pile beams, which form the adjacent parts of the wall. The junction member has interlocking elements on its edges also.

Our invention will be understood by reference to the drawing herewith, in which it is shown embodied in different forms so as to be adapted for use with different forms of steel sheet piling.

In this drawing, Figures 1 to 8 show our junction member provided with interlocking elements of the Lackawanna form. The other figures illustrate other forms of interlocks. Fig. 1 is a perspective view showing the junction member assembled with three simple pile beams. The side interlock nearest the eye is shown unobstructed. Fig. 2 is a similar view in plan to show the possibility of angular adjustment of the simple piles with reference to the junction member. The remaining figures are also in plan. Figs. 3, 4, 7 and 8 show modified forms. Figs. 5 and 9 show the use of our junction members for bracing, stiffening and reinforcing a single wall. Fig. 6 shows the unct-io-n member used in piling structures where main walls are connected by cross walls. Figs. 10 and 11 show our invention embodied in forms adapted for use with the U. S. or ball and socket sheet piling. Figs. 12 and 13 show it in forms adapted for use with piling built up from standard structural shapes. Fig. 1 1 shows a. form for use with Vanderkloot piling.

Referring first more particularly to Figs. 1 and 2, A indicates the peculiar junction member, which is the subject of this applica- Specification of Letters Patent.

tion. This member consists of the web 1 provided on both sides and intermediate of the edges, with the side interlocks C C. These side interlocks, or intermediate elements, are arranged on the web itself and project therefrom only sufficiently for convenient interlocking with corresponding interlocks on the edges of the pile beams, which form the adjacent parts of the wall, or walls. As shown in said figures, these side interlocks G C consist each of a hook 2 and a guard 3, like the interlocks B B on the edges of the junction member; but it is not necessary that the side and the edge interlocks should be the same in form, for they may diifer in form as shown in other figures. The webs are usually straight and uniform in thickness. D indicates the simple pile elements provided on the edges only with interlocks. As shown in Figs. 1 and 2 these interlocks are also of the Lackawanna type and consist each of the hook 2 and the guard 3. On the junction members, the side interlocks are preferably arranged opposite and midway between the edges, a form generally more convenient to roll, but said interlocks might be differently arranged if desired, for instance nearer one edge as shown in Fig. 3, or staggered as shown in Fig. 4. As here indicated the side interlocks may difi'er slightly from those on the edge in outline, but both of the Lackawanna type.

Our new junction members have the great advantage of being rolled complete in one piece from the steel blooms, like thesimple beams and sections, and almost as easily. They are practically the same as the simple beams so far as convenience in handling and ease in driving are concerned. Such uniformity is important, for in handling, piles in large numbers it is desirable particularly in driving, that all sections should give uniform results without ofi'ering unusual problems to the workmen or exceptional resistance to the pile driver. Shapes having enlarged or peculiar sections, when handled in connection with standard shapes of piles, would not only be inconvenient in themselves, but, from the very fact of the dissimilarity, non-uniform and unexpected results, delays and accidents would be likely to arise during installation, of course increasin the cost. Our junction members being there ore similar to the simple pile beams, and requiring no fabrication or special preparation, are

particularly economical to manufacture and convenient for use in the field. They may be introduced into a wall of simple beams at as many joints as may be desirable without disturbing or modifying the wall itself, for the purpose of forming a corner for two walls, or a unction for three or four walls, or as braces, posts and stifleners. T he unction members have all the characterist cs of the simple pile beams so far as rigidity, strength and flexibility of oint are concerned. They are more rigid because the interlocking flanges on the sides reinforce the web. The same range of angular adjustment (flexibility of joint) in the wall is possible, where the members are lntroduced as where the simple piles alone are used. For illustration of this see Figs 9. and 5.

The use of the junction members for connecting two parallel walls by cross walls illustrated in Fig. 6. Where large quant1- ties of junction members are to be used as three way pieces for so connecting two walls, they might be formed with the intermediate interlock on one side of the web only as shown in Fig 7, but generally it would not be profitable to roll such exceptional shapes.

It has often been found necessary, in order to resist the strains to which sheet piling structures are exposed, to tie back the tops of the piling wall with iron rods, or to brace the walls with wooden or metal beams, or to drive additional posts in front of the wall to be connected thereto by bracing timbers. Our junction members used merely as reinforcing pieces (see Figs. 5, 9) add greatly to the rigidity and strength of the wall. When so used, they do away in whole or in part with the aforesaid supplementary parts, thereby saving expense. It will be understood that, when the junction mem bers are thus used as stifi'eners, they may be introduced into a wall at as many joints as desired and generally speaking should be driven to the same depth as the simple beams forming the wall proper, though this is not always essential. In case of bad foundations the junction members or reinforcing pieces may be driven deeper than the simple beams, thus strengthening the whole wall by the increased penetration of these members at intervals. We believe the complete wall reinforced as shown in Figs. 5 and 9 to be broadly new.

In Fig. 5 we have shown a .wall of Lackawanna piling so braced and stiffened by use of our junction members introduced at every alternate joint. The desirability of a stiffener at an angle in the wall is here illustrated. Where the junction pieces are to be used merely as st-ifleners they may be formed without the edge interlocks, as shown in Fig. 8, but we do not consider that form so good.

In Fig. 9 we have shown a wall of the so called J. 8: L. type of piling so stiffened and braced. The wall as indicated is composed of standard I beams 4 and special interlocking pieces 5. Corresponding junction members, used as stitfeners, are here shown having intermediate side flanges 6 (3 to engage with the I beam flanges.

In Figs. 10 and 11 we have shown our junction members shaped for use with the so called U. 5. steel piling. In Fig. 10 the junction member A has its edge interlocks in the form respectively of ball and socket 8 and 9, but its intermediate interlocks C C in the form of inwardly turned flanges 10, to engage with the ball 8, on an adjacent pile section. In Fig. 11 the intermediate interlocks C C are substantially in the form of the ball to engage with the socket 9 on the edge of the adjacent section. Here, as with the Lackawannzfl form of junction member, there is the same possibility of angular adjustment, of course within the range of the particular type of piling. Also in the same way at the joints, grooves are left suflicient to receive the material displaced in driving, promoting sealing of joints and easy driving.

The other figures illustrate modifications in the form of our junction member to adapt it for use with various non-flexible forms of piling, that is, forms which have capacity for little, if any, angular adjustment at the joints.

In Fig. 1.2 is shown the junction member A provided on its edges with the usual I beam flanges 12 12 for use with the composite members formed of I beams 13 13 bolted together according to the so. called Simon or Jackson system. The side interlocks consist of the inturned flanges 15 15, forming rather wide flat grooves for engaging with the flanges of the usual I beams used in this type of piling.

In Fig. 13 is shown a unction member adapted to be used with channels according to the so called Friestedt system. Here the junction member has its edge interlocks formed by the channel flanges 17 and attached Z bars 18 to engage with adjacent channels. The side interlocks C C are composed each of a substantially straight flange 19 and of a single inturned flange 20 to receive the ordinary flange of the adjacent channel.

In Fig. 14, is shown a form of junction member for use in connection with the so called Vanderkloot sheet piling. .Here the edge interlocks of the junction member consist each of the straight flange 2'1 and the hooked flange 25. The intermediate interlocks are correspondingly formed with a head 26 and a hook 27.

We are aware that junction members, so called, have heretofore been produced, but

those consisted merely in riveting one I beam to the flange of another, whereby a rudimentary article was produced, which could be used as a three-way junction member, but not Where two walls intersect, nor to reinforce a single wall. Furthermore these old forms Were more expensive, heavy, large and inconvenient in section, offering great resistance to the pile-driver, and, because so diiferent from the simple pile beams, gave those non-uniform and unexpected results, already referred to. The built-up members involved expensive and troublesome fabrication, and were of uncertain strength because the rivets are exposed to the unusual tensile strains.
